T all whom-'it may concern Be it known that I, JASON C. LOTTEBHAND,

a'citizenfof the United States, residing. inV

New York, in the county of New York and lState of New York, have.invented certain new and useful Improvements .in Adding Mechanism, ofwhich the following is .a specification. I Y

One of the -objects of the present invention is to provide lanimprovedform'of mechanisml in'an -adding mach-marin connection with theadding devices and print# ing devices of any suitable form connectedtherewith, lwhereby the total of the items that have been set up will because-d to print and thereupon the adding' devices will be lrestored tothe zero position.

Another object of the invention is to provide an improved form ofsub-total device in connection with such a lmachine whereby the total ofthe items that have been set up is printed, but instead of the addingdevices returning to zero, thetotal printed is held so that furtheritems can be added to such a total, that is known in the art as asubtotal. l

4A further object is to provide in connection withthetota'l andsub-total mechanism,

.key-operatingdevices that are. simply depressed and held in depressedposition by the machine, and do notreqiiire to'be held down by thefingers of the operator while the main operating member is actuated. i

Another-object of the invention is to provide an `improved form ofmechanism in connection with the adding devices, and a suitable printingmechanism connected therewith, whereby on the operationy of the4actuating memberanumeral or item= set1 up on the key-board will be'printed in the usual manner, but the adding mechanism.l will be lockedso that vthe 'item will-'not be added to the sum already set up in theadd. ing device.

Another object is to provide means inthe forni of a single member.connected with each adding wheel and its coperating column or bank-ofkey` stops, that will serve to lock each rack and type'fplate in normalposition to release, the sameuppnthe advance of any of the-key-stops;which mem- -ber nwill further `.operate when -shifted by aspccialkey-connection `-torestore any-of the key bars ,that mayhavebeeni advanced.

nother object;@Ltheinventlonis topwvide an improved 'form of so calledflexible key-board whereby when any stop bai' connected with a key hasbeen advanced and is found to be not the one desired, the op erationof-pressingv any other key of the same bank will restore the key -thatwas del pressed. n Another object of the invention is to provide animproved form of restoringdevice, that at each operation ofthe actuatingmember, will restore allof the keys that havel been depressed; and inconnection with suchy mechanism a single key member that will also serveto restore-all keys that may have been depressed. Another object of theinvention is to proride 'means-'whereby a form of retarding delicensprovided to regulate the return move- Fentof the mainl actuating shaft,in con ection with a'universal barand'the adding eclianism, wherebycertain dparte of the adding mechanism areinove or. restored ltfter theuniversalbar is brought to rest,

and each movement of such-parts is controlled by the saidretardingdevice.

In the drawings the machine is shown as mounted on a suitable base 1that is provlded with side plates 2l and 3, supporting con-v f chine.

For each of the columns is a set of stopbars, that coperate with a rackand type plate, the latter serving to control an adding pinion. Each keystem 7 is pivoted to a crank 8 swinging on a supporting plate 17. Thecranks 8 are each pivoted to. a stop bar 9 extending horizontally andsliding in slots 11 in a vertical transverse plate l0.' It will beobserved from Fig. 3 that for each column there are nine of these "stopbars having a staggered arrangement, and each one ofthe nine isvertically offset an equal distance from thead'acent one. When a key isdepressed it will swing the crank and advance the stop bar 9 rearwardly,as indicated in Fig'. 1. i A spring'13 is placed on the end portion ofeach lstop bar 9 engaging by its ends theplate 10 and a cross bar 14 onthe bar, respectively, tending t-o force the stopb'ar forward until alug 15 on the stop bar enga es a stop plate 12, similar to the plate ll0w ich .is the normal position of the stop bars. But when the stop bar ismoved rearward, the inclined face of the lug 15 will strike a pin 216 ona vertically movable latch-plate- 16 and elevate the latch-plate,

and after the lug passesthe pin the latch plate will drop so that thepin will lie opposite the abutment face of the lug 15. When `the key isreleased by the finger, the spring will force the stop bar-forward untilthisI -pin strikes the lug 15, as indicated in Fig. 2,

that will arrest the stop bar inthe advanced position. The latch plate16 is supported by a link 18 atits lower portion and at its upperportion by a lever 19, 'and fis pulled downwardly by a spring 20connected with an extension 21 on the latch plate. The latch plate isprovided with nine of these pins 216, four Aon one side and five on theother, positioned to coperate with'the nine.

stop bars?. ses ectively, each latch plat-cibeing intel-pose between'the two rows censtitutng eachoup of stop bars, as indicated in Fig. 3. Iany latch bar of. a set has been \advanced and its lug locked behind thepin, as indicated in Fig. 2, the depression of another key to advanceits stop bar. will cause the lug on such stop bar .to strikel the pinand raise the latch bar. This raisiiig of the latch bar will move all'of the pins'away from. the stop bars, and thereforeany latchbarpreviously advanced will be released from the pin and moved forwardly bythe spring 13 thereof. By this means when any key has been depressed ina column and it is desired to have it-restored and another key bedepressed, it ,is only necessary to depress the proper key, when theprevious key will be restored. c

Means are also provided for simultaneously raisin all of the latchplates 16, a rod 22 beinU s own located below th'e lower end of thellatch plates carried on arms 23 and 24, and also connected by a link 25with a lever 26 that is pivoted at 27 on one of the side plates. Whenthis lever is swung by depressing a key 28, the rod 22 will be elevated,raising all of the latch lates and releasing all of the stop bars t atmay have been advanced.

vMeans are further the bar 22 to shift al of the latch plates, each timethe actuating `shaft for themachine is operated to add or print an itemset up bythe keys. A shaft (see Figs. 1 and 4) extends across the baseat the forward part of the machine that is shown as operated by a handle61. I On the shaft 60 is a crank 35'carrying a pin 36. This pin isarranged to coperate with a latch 29 pivoted on the lever 26 in thenormal'position' of the latch, as indicated in Fig. 1, 4the pin swing-'ing the latch down as the crank and pin move f orward, but on thereturn'stroke the pin strikin the latch toswing the lever 26 and raise te bar 22. Connected with the.

latch 29 is a link 30 arranged to be engaged b f apin 31 on a key stem32, that is-pro vided jwith a ledge 33 arranged to engage underthe-plate f5 when this key is depressed and held 1n such position by aspx-lng 34. The depression of this key will swing the link 30 to shiftthe latch to the position indicated in broken lines in Fig. 1, wherebthe'pin 36 will move freely past the latc and not serve to shift thelever 26. This constitutes the repeat key whereby when any keys havebeen depressed to set up an item it will remain set up and this numberwill be added and printed for each successive operation Aof the handle.But moving the key 32 forward will release its shoulder fromthe plateand it will be restored by the spring 34, permitting the lever 26 torestore all of the key bars as described.

Means are also provided for locking the keys against any movement afterthe initial rovided for raising that is movement ot the handle and shaft60 so that no' other keys can be depressed or any changes made in thekeyboard. A bar 37 is mounted to swing on arms 38 mounted in the sideplates'respect-ively, (see Fig. 1,) which barengages the extension 21 ofthe levers 19 in the position shown, and preventsall of the lat-ch barsfrom rising. One arm 38 is provided with a cam 40 that en- -vgages a pin39mounted on a side bar 53 pivoted to acrank pla-te 59 carried hui theshaft 60,"and yhence reciprocating' from the handle. (See Fig. L2.) inthe normal rearward positionof the handle and side plate, the pin liesat the cam portion 40 and the spring 41 will drive the bar 37 forn wardreleasing the latch plates. But at the initial movementof the handle andside bar the cam 40 will swing the arm y38 and cause the rod 37 toengage the latch plates and .lock `them against'being elevated. It willbe observed from the shape of the cam that thewbar will remain in this4position during the entire rearwardv movement of the side swing i :rnarm 56 thc links bar and until the iinal portion of its ret-urnmovement. 'so that no change can he madel in the keys after the firstinitial movement of the handle and shaft.

yA rack and type plate 42 is arranged one v for each of the sets of stopbars, each plate sliding vertically on a post 43 that it engages byguides44.. (See, Figs. 1 and 4.) Thepost 43 is `tubularand contains aspring 45 connected with the type plate to draw it upwardly when inthelowermost position. These plates are moved downwardly and normally held.in such position by a universal bar .4G that engages a stop62 at therear of each rack. The bar 46 is carried by Varms 47 'and 48 fast on across shaft 49 at the rear of the machine having bearings in the sideplates 2 and 3.

A crank 50 on one side is fast on the shaft 49 and carries a pin 51riding in a slot '52 in the side bar 53 so that the crank has a limitedmovement bar. pivotally connects to a lever 55 pivoted on the side bar,(see Fig. 10) and provided with projecting-upward to engage a .Stop pin57 at the latter portion of the rearward movement of the side bar, that.will serve to break the alinementof the' link 1n..f:crs`54andv55. Theshaft 49 carries a crank 171 (see Fig. 4) connecting by one or maresprings 170 with a bracket 172 that is; hel-.d stationary. This springtends to he shaft 49 lto move the crank o0 rearw d, and when the bar 53is drawn forward by operating the handle, the pin 51 on theV crank SOwill be held stationary, and .54 and will straighten out put.- ting thespring 458 under tension, that connects pin 51-with-th pivot of link55;' This independent of 'the side,y A link 54 is pivotcd on pin 51y andomaking'- theA pin of the spring' 170. The crank 50 will swing rearwardwith the link still in its straight posit-ion, until the arm 56 strikesthe stop pin 57. IThis will break the toggle link, and the arm 50 isvnow arrested because of stops 180 and 181 engaging the arms 47 and-48bt' the universal bar, which will bring the universal bar to rest in itslowermost posi- Lion. But the spring 58 von the link that )has put undertension when the .link became straight, now that the link is broken tythe pin 57 will draw the Side bar 53 Sau vfart-her rearward. Certainparts of the mechanism, set forth hereinafter, are operatively connectedwith the side bars and as the side 'bar is given an additional movementafter the universal bar and shaft 49 come to rest, certain operationsare effected after the universal baris returned to its normal position.

- It is customary in this art to provide. a retarding means for thereturn of the handie and main shaft, so that the handle can be drawnforward and released and the retarding device will prevent a too rapidreturn of the handle and a too rapid operation of the parts operated onthe return stroke of the handle. A; retardingdevice in the form of adashpot `164 is shown having its plunger 165 secured at the outer end toa cross bar 173. (See Figs. 1 and 4.) The dash pot 164 is carried by ayoke 166 that is pivotally mounted on the shaft 49, but free'to swingthereon. 'An arm 167 extends downward from the yoke 166 and is pivotcdto a. link 168. The latter is pivoted to a stud 169 fast to the side bar53. It will thus he Seen that this dash pot operates directly on theside bar and not directly on the crank shaft carrying the universal bar;whereby the entire return movement of the side bar is under the controlof. the retarding device, and the side bar cannot jump back quicklyafter the universal bar has been brought torest. The rack and typeplates 42 are thus normally held down by the universal bar 46, and whenthis bar is permitted to rise by the operation ot' the handle, and therack and type plates to be carried up by their springs until the stopsloo 63 at the front of each rack and type plate,'

engage one of the stop bars 9 that has been advanced, as indicated inFig. 1 this will arrest that particular rack and type plate and theuniversal bar will rise free there from for the-remainder of itsupwardmovenient.= These platesf42 have'a,I rack 73.011-

meral pinions 74 when the pinions .are-

shifted intothezpath oftherack bars. Each rack and'tyge l-plate 42hasacarrier portion 64 in" w,ich1are arranged a set of type 65 in the-form ofplungers. The printing mechanism `forms no part of the presentinventlon, ibut 'a form- .of ysuch operating mechanism'will, bedescribedfor. the sake of clearness, s ee Fig. 22.

A set of'type hammers`66 are pivotally mounted and each is swung by atrigger 71 mounted on a shaft 72 connected with the arms 47 and 48. Whenthe trigger moves rearward, its ,hook 70 engages tips 69 on 1 theprinting of the numbers as desired from the position of the stop bars.The triggers '71 will serve to operate the hammers at the latter portionof the stroke of the lside bar that elevates the' universal bar 46, andthis will Vbe referred. to later in regardto the printing of the 'totalsand the sub-totals, because when a total isprinted the adding device visreturned to zero, while when a sub-total is printed'the adding device isrestored to its tptal'that has been printed.

IThe numeral pinions. 74 are mounted free .i toturn on a Shaftl 75'extending acrossv the machine and carried by supports in the form ,of'anarm 76 on one side of themachine fand a lever 77 on theother side of themachine lrocking on a pivot 183. By shifting this shaft 75, the pinions74 can be shifted from engagement with the rack bars 73, to a positionfree from therack bars. When the rack bars 73 are reciprocated adistance governed by the positioned stopbar 9, vthe pinions 3 in meshtherewith will be rotated a corresponding distance. The 'pinions areheld in engagement withthe rack barsidur-l -ing their movement in onedirectiononly in thenormal operation of the machine, and by swingingthese levers the pinions are moved to disengage the rack bars duringtheir movement. in the other direction. In

this particular machine, in the normal adde'fitffe appropriatepositioned stop bar. There' ing operation,'the pinions will be held awayfrom the rack bars, as indicated in Fig. 10, and after the keys havebeen depressed to position the stop-bars 9, the swinging of the handleand consequent rising of the univer-- sal har 4:6 will permit the rackbars to rise by .their tensioned springs, until thel stop on 4theforward part of the rack bar engages upon, .by means hereinafter setforth, the pinions are allfshifted rearwardly to engage the rack barsand hold them engaged uring the returnmovement of theV 'rack bars causedby the return of the universal bar.v Thereupon, the. pinions will be'"rotated la distance' corresponding with the' movement. of the rack bars,that. is controlled by the stop bars.

Carrying mechanism is provided for each numeral wheel, except, the lastwheel on the left hand side, whereby as each wheel com.- pletes arevolution and begins the second revolution the carrying .operationtakes place to advance the wheel or pinion of next higher denomination asingle number. This mechanism is operative to be set during the rntationof the wheel in engagement with the .rack bar, but thecarrying-operation is not, done at such time. At a subsequent stage inthe operation, after the pinions are all moved forwardly to disengagethe rack lbars and the rack bars `are returned to normal position by theuniversal bar,

then such set members are caused to effect the carrying operation.

The mechanism for the carrying operation comprises essentially a toothedsegv ment lever and an operating detent lever for each of. the pinions.In front of each pinion 74 isan elbow lever 93 (see Figs. 16 and 17)that are all mounted on 4a stationary shaft80 supported in the sideplates. Each elbow lever has a segment arm 79 projecting rearwardly andprovided witfd'teeth corresponding with the teeth of the pinions 7 4,and these segments are positioned so that immediately upon the pinionsbe' g swung forward-and dlsengaging the rac s 73, they will engage thesesegments, whereby the pinions are constantly controlled by one of thesetwo members. -lt will be seenthat when the pinions engagev the rackbars, the toothed segments are free to swing, as indicated in Fig. 1.But when the pinions are shifted forward, as indicated in Fig.' 16,rocking of the elbow lever 93 will turn the pinion 74 the same directionin which it is turned by the downward movement of the rack bar inengagement therewith. Each lof the elbow levers has a' downwardly eX-tending arm 8l provided with an ear 82 extending to the right toward thepinion of lower denomination. A spring 89 connects each arm 81 with asuitable part of the machine, tending to dra-w the arm 81 rearwardly toswing the toothed segment upwardly from the position shown in Fig. 17 tothat. shown in Figgl; and if the pinion engages the segment at such timethe same will`be advanced to-ei'ect the carrying op- -ertienf 'or eachof the elbow levers 93 there is a de'tent lever 94 shown separately inFig. 21, having an arm 83 projecting forwardly and spring.

provided with a catch 184. These levers all swing on a stationary crossshaft 84, and are Apositioned to have each catch 184 cooperate with theear 82 on the depending arm 81. A spring' 88 connects the arm 83 with apiece 185 connected with the shaft 80, tending t-o swing the arm 83upwardly into engagement with the ear 82, thereby causing the ear 'toengage the catch 184, as indicated in Fig. 17, whereby thisl catch willvprevent i rearward movementof the arm 81 by its lVhen the detent 94 istripped as Athe arm 83 swings downwardly so that lthe a restoring' bar90 carried byarrns 91`and 92 swingirnggj.v on Aoppositel sidesof themachine catch releases the ear, the spring 89 will draw the arm 81lrearward causing Athe toothed segment to swing the vpinion if thelatter is shifted forward in engagement therewith.

The detent 94 is provided with anupwardlyextending arm 85 provided witha stop 8G at its upper end. vIt will be observed that the arm and stop86 is offset to the right a short distance from the pinion correspondingv@ith the toothed segment whose lever and ear engage this detent` thatis, coperate with thefpinion of next lower denomination. Each of thepinions 74 is provided with a lug or cam 87, that, when the wheel isswung inthe direction of t-he arrow, will strike the stop 86 to move thearm 85 forwardly and swing the detentarm 83 downwardly, thereby trippingthe detent I to free the ear 82 of' the elbow lever 93.

dicated inv Fig. '17, in which position of the f parts the toothedsegment is free from the pinion. -It isy by this mcwement 'of the rackbars that the p'inions are rotated causing the cam 87. toswingfthedetent-lever-to trip the elbow levers 93.' Therefore mea-ns arevprovided for engaging. the elbow levers to arrest their free vmovementand to hold 'them tripped from the detent arm untilin a sub sequent'stagev the pinions 74 have been shifted forwardly, disengaging'the rackbars and engaging the segment .arms Thereupon therelease of the elbow'levers will permit them/to be swung by their actuating springsaljsuflicient distance ,to-turn the .pinions a singletootln'to advancethema 'unit distance. This `function is accomplished 'by on the sideplates.

The bar 90 `is normally held a short dis-v tance o-i'set lfrom the lowerend of 'the arm 81, whereby when thegdetent is swung by the caintorelease the e'ar v82', the arm 81 can be vswung by its springeshortdistance to pass the catch 184 and prevent rengagement when thecani leaves the stop 80ofthe i ment arms.

the detentis trippe detent. The carrying levers are held in tn's'lposit-ion by the restoring bar until the pinions are swung forward toengage the seg- Then the bar 90 is shifted rearwardly which will permitthe elbow levers to be lswung by their springs a suilicient distance toturn the pinions a unit distance to carry. It will, of course, beunderstood that all of the elbow levers and corresponding detents areindependentq and only those tripped bythe cam 87 will be permitted toswing when the `restoring bar moves rearwardly. Then the restoring bar90 is moved forwardly, it will engage the depending arm 81 and swing itforward, thereby permitting the ears 82 to rengage the catch 184011 thearms 83. But the latterjoperation is not effected until the pinions havebeen swung rearward free from the segment arms 79. l

The means for operating the restoring bar 90 in vtimed relation to theoperation of the'universal bar 46, and also for, operating the lever T7to shift the numeral pinions into engagement alternately( with the rackbars and with the segment arms, is as ffollows:

is engaged by an arm 107 carried by the.

bar 5 3, at `the extreme forward movement of the bar, and thereby thearm 92 will be swung'to move thc restoring` bar 90 forward.

'An elbow lever has onevarm 98 provided with a catch 981 arranged toengage a lug 90 on the arm 92, to thereby lock vthe arm 92 and preventits being returned by a spring 88. But the latch is so positioned thatthe bar 92 can be given a slight rearward movement on the return of thebar 108 before .these parts 96 and 981 engage to lock the restoring vbarin such position. This is for the purpose of Swingin the depending. arms81 sufliciently forwar to permit the detent arm to rise and engage thecatch with the ear 82, and thereupon the restoring bar that vwill beheld by the latch 98, will be offset a slight distance from thedepending arm 81.

This' will also permit the slight rearward movement Iof the de endingarm 81v when The further rearward 'movement 'of the bar 53 will notinteriere with the position of the arm 92 and the restoring bar until -adepending arm 982 of the elbow-lever, that is held in latehed positionby a spring 100, is engaged by a pin983 on the bar 53 to cause thiselbow lever to be tripped, releasing the arm 92v andthe restoring bar.But this engagement 'of the pin 983 with the arm 982, by the posift-ionof Ythe pin, is not effected until the final part of the rearwardmovementof the bar 58,'fater. the universal bar has been returned to itsnormal lowermost position and las' ' the toggle bok'hg as hasbeendescfibed.

' and hence nee The arm 91 engages a stop pin 910 when drawn back by'its spring 911. (See Fig. 5.) 0n the opposite side of the machinel asimilar construction is provided, (see 7) the: a'rm 97 being drawnrearwardly y a spring 99 to engage a stop pin 101. A bar 200'is 'pivotedto the arm 91 and guided at its slotted 'portion 202 ona pin 203. Thisbar 200carrie's a lug 204 that is engaged by an arm 205 y:tast-on a bar120 corresponding to ther-bar" 5 3 on the 'opposite side of themachine'.- The shaft' 60 operated by the handle l61, v entendsa-crosstheQmaC-hne and on the left side carries a crankv arm 126' backand forth in unison. from the operation of the handle' and the mainsprin By the said means the arms 92 and 93 wil be similarly controlledby the bars 120 and 53. An elbow lever 97 engages a lug 95 on the arm 91similar to the opposite side of the. machine, anfd a pin 101 on the' bar120 trips this latch in the same manner, the latch being controlled'by aspring 99.

The side lever 77', by means of which the numeral pinions are shifted toengage alternately with the rack bars 'and with the toothed segments.extends downwardly 'on the left side of the machine, (see Fig. 5,) andis pivoted to a bar 144. The forward end of this bar carries a pin 145yriding in a suitable slot in the side frame to guide this bar. The'bar120 is provided with a slot through 'which the pin 145 extends', and asthe bar 120 moves back and forth the end walls 146 and 147 of this slotalternately engage the pin 145 at the extreme forward and' rearwardparts of the movement of this sidebar. By this means, the arm 77 will bealternately swung back and forth a -sufficient distance to carry thepinions to engaging position. `Suitable means' areprovidedfor holdingthe lever 77 in these two positions, shown in the form of an arm .140,pivoted in the frame, and carrying a stop pin 141 having its upper edgein the form of a ridge. This arm is pressed upwardly by a spring 142 toengage alternately with notches 143 in the lower edge or end of the-lever 77. These notches will be engaged by the pin at the two saidextreme positions of not be further. described. The bars 120` and.53will therefore swingV the lever and retain the pinions in said' positionsuntil shifted by the reverse movement of the bar 120.'

In the construction of this machine suitbaits of a row, or

none of the keys and stop h k b ,t erac arcor-- rows, have been depressei responding therewith is locked in its normal lowermost position andprevented from rising .with the universal bar. In front of each of therack bars isla lock plate 151, shown in Fig. 14, that is 'provided witha spring 210 pulling it forwardly and upwardly. This plate has a bentportion 1 56 arranged to be engaged b the extremity of the stop bars 9fso that Vw en any stop bar is advanced it will cause the plate 151 toswing rearwardly.

`The bent portion 156 engages a projection 63 on each rack bar in thenormal position of the plate 151, but when this plate is movedbackwardly 'b the stop bar, as described, the rack bar will e free torise upon the swinging of the universal bar." Therefore, in each rowwhere no key is depressed, this plate will arrest the rack bar andprevent its elevation when the universal bar rises. The

plate 151 also carries a stop in the form of a roller 157, see Fig. 14,positioned just above able'mec'hanism isprovided whereby when the lever19 as shown in Fig. 1, whereby .upon depressing the plate 151, that isnormally suspended by a spring 210 connected with a stationary part ofthe machine, this lever 19 will be swung to elevate its top latch plate16, thereby restoring any keys of that particular bank that may have-been advanced by the depression ofthe projecting end 152 of the plate.vThis constitutes what is termed the column release.

Means are further provided for swinging the wholeset of stop plates 151lrearward t0 shit'the bent portion 15,6 out of enga ement with the stops63 on the rack an type plates'. A shaft 158 is mounted in the two sideplates and carri-es a shutter 159 that, when the shaft is swung, willstrike the lower portion of the lock plate and sw-ing it rearward. Thisshaft 158 at the left side of the machine, 'carriesea crank 160, seeFigs.

On'this sidebar is mounted a lever 127 swinging on a pivot128, the lever being normally pulled vupward at its rear .end by aspring 137. and 8.) But when the lever 127 is pulledA Y upward at itsfront end by means described hereinafter,it will engage the pin 161 and'place the pin in position' to engage the front curved end of the cam163, and upon forward movement of the side bar 120-fromswinging ofthehandle, the crank 160 willl be swung downward to rock the shutter,and shift theshut'ter rearward, causing the stop (See Figs. 7

-or ledgev 131; that plates to release all of the rack and type bars.This is done when it is desired to take a total, or a sub-total, on themachine.' i

At one side of the machine is a total key 132 vertically movable andcarrying a pin 135 engaging a spring 134E to normally move the keyupward. At the lower end of the key-stem 132 is a hook portion 133 thatwhen the key is depressed, will engage a similar hook 130 carried by theswinging lever 127, as indicated in Figs. 8. and 9, the stem and leverhaving a certain lateral movement from4 resilient construction. When thekey Ais depressed these hooks...will..engage and upon release the keywill move upwardly and swing the lever 127. This will hold the leverswung for a certain period, to operate the shutter 159 as justdescribed, releasing all of the rack and type .plates from the said stopplates 151. On the side bar 120 is a stop projects over the lever 127and is engaged by the top edge of the same when the stem 132 isdepressed to hook on to the lever hook indicated in Fig. these parts,and the handle being swung forward, the side bar 120 will move forwardcarrying withit this lever 127 that is pivoted thereon. This forwardmovement will carry the lug 129 forwardbeyond the Vhook 133 of thekey-stem, thus releasing lever 127, the hook being retained lowered bythelug 131 on the sidebar. But during this operation the side bar hascarried the cam 163 forward during thgdepressing of the crank 160 by thepin ll'en'ghged by the lever, so that the pin 161 will be held down`during the balance ofthe forward movement of the side bar;V by this camplate 163. As the side bar continues forward av lug 130 on the lever 127 higher than lug 129,1noves over-the hook, portion 133 so that uponfurther movement of the side bar the hook 133 disengages the ln 131 andengages merely the lug 130. rVifhen the hook 133 .of the stem of thelever, its forward end was again depressed by its spring 137,but whichdid not bring the lug 130 below the plane of the lug 131, on the keystem. Therefore the engagement of this lug 130with the hook 133 of thekey stem will permit the latter. by its spring to be elevated and swingthe front end of thelever 127 to depress a second time.

It is to beunderstood that the lever 127 has a slight lateral spring movement, orthe key stem, or both, by reason of their resilient On depressing thiskey and thus engaging its hook, it will be held dcpressed after thelever 127. is ,swung upward a short distance. But assoon as the side bar120 starts to move forward, the lug 130 is carried beyond the hook 170of the .key stem, thereby releasing the key stem to rise to normalposition, and also permitting the lever 127 to return to normalposition.

YUn the left side of the machine above the 5-9, a bar 230 arrangedadjacent the key stems -and 175, and atits rear end is supported bycrank whereby this bar can swing up yand down.

Butwhen the side bar 230 is de#` pressed by pushing down either the totalvor sub-total key, through the link' 116 and lever 112, the shaft. 111will be rocked, and

the two side bars 200 and"103 will be elevated by the respective links`108 and 220,.

Hence the' reciproca,- tion of theside bars. will notcause engagef ment of these lugs' 106 andl 204: Gwith the' stops on theside bars, and the arms will notI swing the` restoring bar 90.

The lever 127 vthat is pivoted on 'thejside bar 120. carries a lug 136thatl -when the bar can engage the pin 138 onf the inner face of theside lever 77, which latter-"serves to shift the numeral pinions intoandfout of engagement with the rack 73.- In the normal reciprocation vofthe'lside'bar 120, the stop 1-36 .is held free from engagement with thepin138. But when the-total ke 132 is depressed,l this stop -136 islowere forward edge of the lug`136 now engaging the pin 145, (ses rig.8,) wurswingahe lever 77, sp that thennumeral wheels are at once throwninto-engagementwith the racks. As soon as the hook 129 leaves' the hook133 of the key stem 132, the lever will swing and' the lug. 4136 willrise disengaging the .pin'138, but thearm 77 will be locked in thisposition by the arm 140, as described.

As the side bar moves forward carrying the lever 127, the hook 129 willshortly dis'- engage the hook 133 permitting the lever 127 to swing upat its rear, thereby freeing the pin 138 from the stop 136. On continuedmovement of the si de bar, after the hook 133 has passed lug 131 andengages the lug 130, the lever 127 will be again swung to the positionindicated in Fig. 7, in which and as soon as the side bar startsforward, .the

ward, the stop 4136 engaging this lug will swing lever 77 to move the.pinions away from the rack bars,-and thereupon the key stem 132 beingfreed from the lug 130 the lever 127 will swing to free-the pin 138 fromthe stop 136; but as stated the lever `7 7 has now been'swung to freethe pinions from the rack bars, which is the normal position of theseparts. But when the sub-total lkey is depressed and the lever 127 isswung, the pinA 138 will Lbe similarly engagedby the 'stop 136 at theinitial movement fof' the side bar to swing thepinions into `engagelment with the rack bar s.v But as described the forward movement of theside bar will quickl disengage the hook" 176 of the sub- Atotal ey 175,whereby' the-lever will be returned to normal position, disengaging thepin 138 from the stop 136. The lever 77 will remain in this positionuntil the turn the lever '77 to normal forward posi tion with thepinionsA 'free-,from the rack bars;

`The operation of 'the device in connection with the total and sub-totalkeys, is as folhave been setup in the machine by the op'- eration of thenumeral keys 7, and the numeral wheels 74 have been set by theoperationI of therack and type bars and other sired to take la total, itis not necessary to Ahandle 61 as is required in some of the ma- 'chinesof this class'.

As soon as the handle isswung, the crank 160 will be shiftedl andthe cam 163 will swing the shutters to release stop plates 151; whichoperation is effected while the toggle links are being straightened out`and hence before any movement lis given to the universal bar 4:6. `Atthe same time the meral wheels into engagement with the rack bars, andthe further movement of the handle will elevate the universal barpermit- `ting all of the type bars to move upward in contact with thenumeral wheels.' It will be understood that when thc adding operation istaking place, the racks only engage the ment, but now the racks engagethe numeral wheels on the upward movement of the racks and hence theywill move the numeral pinions in the reversed direction, that As soon asthe sidebar starts to move rearinal portion of the return stroke whenthe abutment 147 will strikey the pin 138 and ,ref
